FREIGHT TRUCK.

Application filed May 17, 1919.

To all whom it may concern.-

Be it known that I, WILLIAM F. KInsEL, Jr., a citizen of the UnitedStates, and residing at Altoona, Blair County, State of Pennsylvania,have invented certain new and useful Improvements in Freight Trucks, ofwhich the following is a specification.

The present invention relates to car trucks and more particularly to sixwheel trucks for freight cars.

The principal novel features of this invention reside in the improvedside frame members; the improved single piece bolster; the improvedloose connection between the bolster and side frames, this connectionbeing the sole means for holding the side frames in proper spacedrelation; the improved means for holding the central journal boxesagainst transverse movement, the equalizer bars being utilized for thispurpose; and the improved means for supporting one end of the equalizerbars on the side frame members. Other features of novelty will be apparent from the description taken in connection with the drawings, inwhich Fig. l is a top plan view of a truck con structed in accordancewith the present invention, certain parts of one of the side framesbeing shown in section to illustrate parts otherwise hidden;

Referring to the drawings it will be seen that the truck embodying thepresent invention comprises the side frame members F and F loosely heldin spaced relation by the single piece bolster B. The end axles A and Asupport the side frames through journal boxes bolted to the under sideof said frames. The central axle A has journal boxes at its ends onwhich one end of each of the equalizer bars E are supported, the otherends of'the bars bein carried by the frames.

As shown the side frames F and F are hollow and substantiallyrectangular in cross section. The cross sectional shape of the sideframes may perhaps be best defined by the term box section. Furthermore,throughout the greater part of their length they are substantiallystraight. The end portions of these frame members however are taperedand inclined downwardly to a. slight extent. The frame membersadjacentthe bases of the tapered portions are supported on the journalboxes 20 of the end axles, these boxes preferably being standard M. C.B. freight car boxes. The boxes are secured to the under side of theframe members by bolts 21, apertures 22 being provided in the bottomwalls of the side frame members for these bolts. In order to give accessto the heads of the bolts 21, apertures 23 are provided in the top wallsof the frame members, these apertures registering with the apertures 22.The ends of the frame members are forked as at 24: and these ends areapertured as at 25 to provide means for supporting parts of the brakeapparatus. Furthermore the tips of the tapered ends of the frames areoffset so that they are disposed very nearly in the k planes of thewheels of the truck as clearly shown in Fig. 1. The bottom walls of theside frame members are formed with the elongated slots 26, these slotsbeing positioned over the journal boxes 27 of the central axle, for apurpose presently to be described. Adjacent the end boxes 20, the underside of each of the frame members is provided with the hollow, dependingproj ections 28. The equalizer bars E each have one of their ends 30disposed within a projection 28 and this end is formed with an aperture31 for a key 32, the ends of which are disposed in the registeringapertures 33 formed in the side walls of the projections. As clearlyshown in Figure 10, the under side of the key 32 is formed with acentral.

lug 34, the length of which is substantially equal to the distancebetween the side walls of the projections 28 whereby the lug 34 holdsthe key against displacement. The apertures 33 are of greater heightthan the key, so that the key may be removed by first moving itvertically upward from its position in Figure 10 and then pushing it outlaterally through one of the apertures 33.

As shown in Figure 9 the central box 27 is formed with the verticallydisposed grooves 35 on its opposite vertical sides and recesses 36 inits top in line with the side grooves. The equalizer bars E areconstructed to have one end thereof disposed in the said grooves andrecesses. These ends of the bars are also provided with a projection. 37which is disposed within the slot 26 in the bottom of the frame member.In this manner the adjacent ends of the equalizer bars act as keys tohold the central boxes 27 from transverse movement relative to the sideframes.

The bolster is of one piece construction. As shown it comprises the twotransverse spring beams 38 of I section. These beams are connected bythe longitudinal trusses 39, the latter being offset inwardly from theends of the beams 38, so that they are disposed just inside of thewheels 40. As clearly shown in Figures 6 and 7 each of these trusses areformed with a recess 41 in its underside for the passage of the axle A Astrap 42 is disposed across the mouth of each of these recesses andsecured to the under side of the trusses, as by means of bolts 43. Thestraps 42 are formed with the shoulders 44 which engage on the outsideof the lugs 45 at the mouth of the recesses, thus providing a connectionbetween the truss and strap acting to prevent the mouth of the recessfrom being opened up when the truss is stressed, and thus relieving thebolts 43 from carrying all of this load. The trusses 39 are connected bythe transverse girders 46 which are spaced a distance substantiallyequal to the width of the recesses 41. These girders carrv the centerplate support 47 and this plate is reinforced by the diagonal braces 48extending from the corners of the plate to the junctures of the trussesand the beams 38. As shown in Figure 8 these braces 48 are substantiallyof inverted U-shape in cross section.

The beams 38 have their outer sides adjacent the ends thereof formedwith the vertical channels or grooves 49 to receive the projections 28,thus providing a more or less loose connection between the side framesand bolster to hold the side frames in proper spaced relation. It willbe observed, as the bolster is of one piece construction, the channels49 are provided on one side only of each of the beams 38, the oppositesides having no engagement whatever with the side frames. The trusses 39are connected'to and extend between the sides of the beams 38, that isto say, the trusses are not secured to the upper faces of said beams.Furthermore the transverse girders 46 are connected to and extendbetween the adjacentsides of the trusses 39.

The ends of the beams 38 are supported on the equalizer bars E by meansof the coil springs.

Although an embodiment of the invention has been described in detail, itis to be understood that the invention is not thus limited, but includesmodifications and changes which come within the scope of the appendedclaims.
